Deflator

Abstract

A relatively thin, disk shaped device containing a slot in its face, which slot narrows as it reaches the center of the disk so that when it engages the valve stem of a cut-check valve, the valve is deformed without damage a sufficient degree so that the cut-check valve is unseated allowing air to pass either way through the cut-check valve.

I claim: 
     
       1. A deflating tool, for use in conjunction with cut-check valves, being constructed of suitable rigid material having a slot in its body of suitable length and width which tapers from the perimeter of the tool at a suitable fixed rate so as to accommodate the stem of the cut-check valve at its widest part and squeeze the valve stem, without damaging it, as the slot is moved passed the stem, so that the stem deforms a sufficient amount to open the cut-check valve, said surface of the deflating tool slot being smoothly finished so as not to damage the valve stem. 
     
     
       2. The deflating tool of claim 1 in which the suitable rigid material from which it is constructed is polystyrene and made in the general shape of a disk having a diameter of one and three-quarters inches and being one-eighth inch thick. 
     
     
       3. The deflating tool of claim 1 wherein the slot tapers at a fixed rate from one-half inch wide at the perimeter of the tool to three-sixteenth inch wide at the base of the slot, said slot being one and one-eighth inch long. 
     
     
       4. The deflating tool of claim 1 wherein the edges and base of the slot are curved and smooth.
